FloodLights Mod 1.10.2, 1.9.4, 1.9 adds the electric floodlight (powerable via RF, UE, and EU), a small electric one and a carbon based version as well.

Toggle their invert state via shift right click with empty hand, change mode (straight, narrow or wide cone) by using a wrench (and if neither BC, IC2 or CoFHCore is installed, a stick) and right clicking the floodlights. Power usage, range and refresh rate for the lights (how fast they are placed) can be set in the config.
